SIP Trunking

A SIP trunk is a direct connection between your organization and STPvoice. It enables you to extend VoIP telephony beyond your organization’s firewall without the need for an IP-PSTN gateway. Additionally, SIP trunks can carry instant messages, multimedia conferences, user presence information, Enhanced 9-1-1 (E9-1-1) emergency calls, and other SIP-based, real-time communications services. Because it is easier to configure and less expensive to design, operate, maintain, and upgrade, and because STPvoice delivers services at substantial savings, your investment in SIP trunking can give a quick and substantial return on investment.

In addition to VoIP calls, SIP trunks can also carry instant messages, multimedia conferences, user presence information, Enhanced 9-1-1 (E9-1-1) emergency calls, and other SIP-based, real-time communications services. Users can place local and long distance calls with caller ID and call hold over SIP trunks. With all of the benefits that SIP trunking provides (especially the substantial cost savings), it’s no wonder that SIP trunking is a hot topic in unified communications.

Deploying SIP trunking can be a big step towards simplifying your organization’s telecommunications and towards preparing for the latest real-time communications enhancements, but the biggest motivation for most organizations is immediate and substantial cost savings.

Save money on long distance service.

Long distance service typically costs significantly less with a SIP trunk connection.

Eliminate IP-PSTN gateways (or even your entire PBX).

Because SIP trunks connect directly to STPvoice without traversing the publicly switched telephone network, you can get rid of IP-PSTN gateways and their attendant cost and complexity.

Eliminate a redundant network.

Deploying SIP trunking is a logical step towards the goal of having a single, IP-based network, rather than redundant telephone and data networks.

Eliminate BRI and PRI subscription fees.

With a SIP trunk connected directly to STPvoice, you can dispense with costly BRIs and PRIs, replacing them with service that can cost significantly less. Furthermore, with SIP trunking you don’t need to buy lines in blocks of 24 or 32. Instead, you can buy the bandwidth you need, in smaller increments, and at better prices.

Extend the capabilities of your existing PBX with new services from STPvoice.

With a SIP trunk in place, you can extend existing capabilities with additional services, such as E9-1-1 emergency calling or unified communications.

With SIP trunk from STPvoice you can use any type of PBX with SIP support or even without.
